Chrissy has been dating her man for 4 years and has helped raise his 2 kids as their biological mother isn't in the picture. Whenever they're out, Chrissy's man refuses to refer to her as their "mom," only "Chrissy." She feels like it's disrespectful, and she's even worrying that he's holding out hope for his ex to come back in the picture. What should she do?
